摘要：
A prosthetic valve assembly for use in replacing a deficient native valve comprisesa replacement valve (820) supported on an expandable prosthesis frame. The valve(820) may be delivered transluminally or transmyocardially using a thorascopicor other limited access approach using a delivery catheter (920). Preferably,the initial partial expansion of the valve (820) is performed against the nativevalve annulus (916) to provide adequate anchoring and positioning of the valve(820) as the remaining portions of the valve (820) expand. The valve (820) maybe be delivered using a retrograde or antegrade approach. When delivered usinga retrograde approach, a delivery catheter (920) with a pull-back sheath (922)may be used, while antegrade delivery is preferably performed with a deliverycatheter (920) with a push- forward sheath (922) that releases the proximal endof the valve (820) first.
